Power Supply Explained: 80 PLUS Efficiency, ATX 3.0, PSU Wattage Guide, and How to Choose the Best One | Funifytools

1️⃣ The PSU converts AC into stable DC, powering each component safely like a home’s breaker panel or a car’s fuel pump.
2️⃣ A quality unit ensures stability during power spikes and prevents hardware damage from voltage ripple.
3️⃣ Look for high efficiency (80 PLUS Gold or better), ATX 3.0/3.1 support, and full protection circuits.
4️⃣ Choose reputable brands with ample wattage headroom—your PSU quietly determines your PC’s reliability and lifespan.

Understanding Computer Components: A Complete Look Inside Modern Systems | Funifytools

Image
Most computers follow the Von Neumann architecture: programs and data share memory; the CPU fetches and executes instructions sequentially. CPU is the brain for arithmetic/logic/control—often with NPUs—while the motherboard is the nervous system linking all parts via buses. RAM is fast, volatile short-term memory for active tasks; storage (SSD/HDD/NVMe) is long-term, persistent data. PSU supplies stable DC power; GPU accelerates graphics/video and many AI workloads; I/O devices let you interact; the case cools and protects. Together they form one system—same principles power phones like the iPhone, just in a tighter, integrated form.
